BOX-ENDING MACHINE.

:SPECIFJECATION forming part of Letters Patent No. 743,642, dated November 10, 1903. Application filed February 3, 1902. Serial No. 92,299. (No models To @ZZ roh/0m, t rin/wy concern;

Be it known that LVCLRENCE W. Hoses,

a citizen of the United States, residing at lVorcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in BOX- Ending Machines, of which the following is a speciiication,'accompanied hydrawings forming a part of the same, in which- Figure l represents a side view of a boxending machine embodying my invention. Fig. 2 is a front view of the same. Fig. 3 represents the upper portionof the machine with the platen shown in vertical sectional view and with a horizontally-reciprocating box-end carrier at the rearward end of its movement. Fig. 4 represents the same with the carrier at the forward end of its movement. Fig.v 5 is a top View of the carrier. Fig. 6 is a sectional view through the platen on the plane of the vertically-reciprocating needles for supporting the box end. Fig. 7 is a View, on a larger scale, of one of the needie-holders. Fig. 7a is an end view of the same. Fig. 8 is aperspective view of a boxbody provided with flanged ends to receive the pasted box end. FigpQ represents the under side of a box end, showing the pasted margins; and Fig. l0 represents a top view of the box-form for supporting Vthe flanged end of the box-body.

Similar reference letters refer to similar parts in the different views. n

My invention relates to that class of machines for applying rectangular pieces of carding a box-body in proper registration with the box end; fifth, apressing mechanism by which the pasted box end is pressed firmly' against the flanged ends ofthe box-body, and,

I sixth, means forsupporting the box end above the box-bodywhile the pressing-surfaces are coming together.'

My preseutinvention relates particularly to the sixth or last instrumentality-viz., means for maintaining the box end above the boxbody while the pressing-surfaces are-coming together; and it consists, broadly, in the employment of performing-needles arranged to pierce the box'end and support it during the time the pressing-surfaces are coming together; and it consists in the construction and arrangement of parts, as hereinafter described, and pointed out in the annexed claims, by which this result is accomplished.

For the better understanding of the character and operation of my present invention I have kshown in the accompanying drawings a side and front viewofau entire box-ending machine with the instrurnentalities for supporting the stack of box ends, pasting and feeding the same, and pressing the pasted box end upon the hanged end of the box-body.

` A A represent vertical sides, forming a part of, the-framework of the machine and Ysupporting at their upper ends a platen B,

which forms the upper member of the pressing mechanism. The sides A A are provided with vertical Ways A' A for a vertically-reciprocating bar C, provided with an Overhanging bracket C', upon which is supported a box-,form C2, which forms the lower memv*ber of the pressing mechanism, and is provided Vwith a rectangular upper surface C3, upon which the flanges a of the box-body rest during the operation of pressing the boxbody and the pasted box end together. The platen B has a rearward extension B', upon which are supported vertical guide-plates D, which inclose the stack orpile of box ends D', each of said box ends consisting of a rectangular piece of cardboard b, Fig. '9, adapted to have its pasted margins applied to the anges oof the box end, and thereby form the end of the box. Beneath the `stack of box ends D is a paste-box E and oscillating fingers E and E3, carried upon an oscillating shaft E2 and arranged to have their tips immersed in the paste held in the paste-box E Ico at one oscillating movement and upon the reverse oscillating movement to have their pasted tips carried into contact with the front and side margins of the lower box end in the stack D', thereby applying paste in spots c, as shown in Fig. 9. The pasted box end is carried forward from the stack D to a position between the platen B and box-form C2 by a horizontally-reciprocating carrier F, provided with a boX-end-supporting surface F' and a shoulder F2, engaging the rear edge of the box end, by which the box end is pushed forward beneath the under surface of the platen B and into proper position over the box-form O2 to register accurately with the flanges a of the box supported upon lthe boxform and in position to have its pasted margins attached to the flanges of the box-body by the upward movement of the box-form. The vertically-reciprocating movement of the box-form O2 is produced by means of cranks G G upon the ends of a cam-shaft H, said cranks being connected by links Gr' G' with the vertically-reciprocating bar C. The carrier F is moved by an eccentric I on the camshaft H through an intermediate mechanism consisting of links I' I2 and swinging lever I3. The pasting-fingers are oscillated by a rackandpinion mechanism comprising a rack J, to which a reciprocating movement is given by means of an arm J', extending from a sleeve J2, capable of oscillating upon the rocking shaft J 3. The sleeve J2 has a second arm J4, carrying a cam-roll J5, which runs in a suitably-shaped groove in a cam J6 on the cam-shaft H. Rotary motion is imparted to the cam-shaft H from a driving-shaft K by means of a pinion K' on the shaft K and a gear K2 on the cam-shaft I-I. Motion is imparted to the driving-shaft K by means of a belt-pulley K2, having a belt connection with a main or counter shaft.

The pasting-fingers E' are aranged in a row, as shown in Fig. 2, adapted as the lingers are oscillated to apply paste to the forward margin of the box end. The pasting-fingers EB project radially from collars (shown by broken lines E4, Fig. 2) adj ustably attached to the oscillating shaft E2 and arranged to apply paste to the side margins of the box end. The ends of the radially-projecting fingers E3 for pastingl the side margins of the box end are concentric with the axis of the oscillating shaft E2, and their oscillating movement is synchronous with Yand corresponds to the forward movement of the box end over 4the pasting-fingers, so that spots c of paste will be successively applied to the side margins d d of the box end, Fig. 9.

The construction and operation of the machine as above described are common in boxending machines now in general use. My present invention relates to the device hereinafter described for maintaining the box end in proper position to register with the flanged end of the box-body, which is held on the box-form while the box-form is moving upwardly to carry the box-body into contact with the box end and press the two firmly together in order to allow the horizontally-reihe box-form C2.

ciprocating carrier F to be withdrawn from between the box-form and the platen. I accomplish this result by means of a pair of needles L, held in a pair of needle-carriers L', capable of a vertical]y-reciprocating movement in the guideways of a framework L2, supported upon the platen B. The needlecarriers L' are pivotally connected to the free ends of radial arms N, carriedy upon a rockshaft N', journaled in brackets N2 upon the platen B. The rock-shaft N', journaled in brackets N2, has an arm N3, which is connected by alink N'* with the arm N5 of a rockshaft J3, journaled in the sides A A of the machine and carrying an arm N7, provided with a cam-roll NB, running in the groove of a cam N9 on the cam-shaft H.

The needle-carriers L' consist-of a pair of rods, each of which is hollow at its lower end to receive a needle L and is provided with a diametrical slit L3 to allow the carrier to be pinched against the needle by means of a ring O, fitting a tapered surface O' upon the needle-carrier. One of the needle-carriers is shown on a larger scale in Fig. 7, and an end View is shown in Fig. 72. The needles L project a short distance below the lower ends of the needle-carriers L', and the needle-carriers are depressed by the action of the cam N9 during the period of rest or at the forward dwell of the horizontally-reciprocating carrier F at the end of its forward movement, causing the projecting needles to pierce the box end as it is supported upon the forward end of the carrier. The forward or supporting end of the carrier F extends beneath the reciprocating needle-carriers in order to support the box end against the downward pressure exerted by the needles as they are forced through the box end, and the carrier is provided with grooves P P, which are open at their forward ends to allow the needles to enter the grooves and enable lthe carrier to be withdrawn from between the box-form and the platen, leaving the box end supported upon the needles L, as shown in Fig. 4F. As the box-form C2 approaches the platen the cam N9 lifts the needle-carriers L and withdraws the needles from the box end, leaving the box end free to descend with the box-body. The withdrawal of the needles L from the box end oecurs during the time thebox end is being pressed upon the iianges of the box-'body and While the box end is still in contact with the platen,so that the platen serves to strip the box end from the needles as they are raised. After the removal of the horizontally-reciprocating box-end carrier F the box end is supported above the box-body by its frictional contact with the needles L, and as the needles L are held from lateral movement by the insertion of the lower ends of the needle-carriers in the holes Q of the platen as well as by the framework L2 the box end is maintained in accurate registration with the box-body held upon I prefer to lift the needles out of the box end before the latter comes in IOO IIO

contact with the box-body, and the needles may be short enough to allow the flanges of the box-body to be brought very near to the pasted margins of the box end without hitting the points of the needles; but longer needles may be used and the upward movement of the needle-carriers delayed until the boxbody is actually brought into contact with the box end by forming small recesses or openings Rin the upper surface of the boxform C2.

What I claim as my invention, and desire to secure by Letters Patent, ls-
